LUDWIG STOLLWERGK, OF COLOGNE-ON-THERHINE, PRUSSIA, GERMANY, ASSIGNOR TO JOHN H. VOLKMANN, OF NEW YORK, N. Y.

VENDING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 384,939, dated June 19, 1888. Application filed February 25, 1888. Serial No. 205,278. (No model.)

To all whom it 11mg concern:

Be it known that I, LUDWIG SToLLwERoK, of the city of Cologne-on-the-Bhine, in the Kingdom ofPrussia and German En1pire,have invented a certain new and useful Improvement in Vending Apparatus, of which the fo1- lowing is a specification, reference being had to the accompanying drawings, and to the let-" tors of reference marked thereon.

This invention relates to an improvement in apparatus for the delivery of prepaid goods; and its object is to prevent the coin once paid into the apparatus from dropping into the cash-box without delivering the prepaid articlea difliculty which is now often experienced with apparatus of this kind as heretofore con-- structed, particularly in such cases where children were too timid to pull out all at once the drawer delivering the prepaid article.

In the accompanying drawings,forming part of this specif cation, Figure 1 is an end view of my improved apparatus, the casing thereof being 'partly cut away. Fig. 2 is a side view partly in vertical transverse section; and Figs. 3, 4, 5, and 6.illustrate modifications hereinafter referred to.

Referring to Figs. 1 and 2 of the drawings,a is a conduit into which the coins are dropped by the purchaser, and b is a spring the one end of which is fixed to the rear side of the conduit a, while its free end carries the pin 0. Below the money'couduit a is arranged a skeleton drawer, e, in connection with the free ends of the coiled retracting-springs f, by means of which the cross-bar g of the drawer e is held normally against the lower free end of the spring I), so that the latter is pressed backward and its pin 0 drawn out of the conduit a,which it will enter through an opening or slot under the action of its spring I) when the latter is not acted upon by the cross-bar g.

The cross-bar g is provided with a slot, h, which in the normal position of the drawere is in line with the money-conduit a, and below the sloth is arranged a bar, i, provided with steps is, and having the slot or opening k at its front end. The steps k are arranged so that the inclined upper surface of each step is rising in the direction from the money-conduit a toward the slot 7e, and the rear side of each step is vertieal,or nearly so, in relation to the plane of the drawer e. The drawer e islarranged so as to slide upon the brackets l and passes through the funnel-shaped box m. The forward end of the driver is provided with a crossbar, c, or other handle, by means of which the drawer may be shoved to and fro. Above the drawer e, on each side of the casing A of the apparatus, are arranged the brackets d, sustaining the lowermost of a pile of packages of chocolate, tobacco, and similar articles for sale piled the one above the other.

A coin, n dropped into the money-conduit a, will enter the slot h int-he cross-bar gof the a drawer c, the retainiugpin a being pushed out, 6 of the conduit a by the cross-bar g of the closed drawer being pressed against the lower end of the spring I), as shown in dotted lines in Fig. 2 of the drawings. The said coin is held by the bar 11 within the slot h, so as to project therefrom above, and will thus catch behind the lowermost of the pile of articles n, resting upon'the brackets d, so that on pulling the drawer 6 forward the said article or package i will be drawn out through a slot, it, connect- 7 ing the box m with the interior of the casing A. The article thus drawn out will drop into the box m and come-out through the opening a at the lower end thereof, so that it can be taken holdof by the purchaser, whilethe coin will fall through the opening is into the cash box or receiver B.

It will be seen that the coin can drop into the box B only after the package has been pushed through the slot at and delivered into the box on, and that it is impossible to push back the drawer unless the package has been delivered, for the reason that so long as the coin is behind the said package it is prevented from returning by comingin contact with the vertical sides of the steps It on the upper surface of the bar i, as will be readily understood. Moreover, by the arrangement described of the spring b having the retaining-pin c] it is rendered impossible that a coin can drop from the 5 conduit a in case that the drawer e is pulled forward prematurely. This arrangement of the spring I) and retaining pin 0 will also allow of inserting into the conduit a two or more coins at a time, in order to obtain two or more I00 springs 15".

packages of chocolate or other article for sale. The apparatus will thus deliver justthe quantity of articles paid for,and the purchaser,not as heretofore, lose his money if he pays into the apparatus more pieces than necessary.

It is evident that instead of the rigid steps 76, I may as well arrange in the path of the moving coin movable steps 7c, constructed as before described, which are depressed by the coin on its way to the slot 70', while they will preventits retrograde movement, such modified arrangement being indicated in Figs. 3, 4, and 5 of the drawings.

In the arrangement shown in Figs. 3 and 4 the bar z'has been replaced by a plate, 2', provided with a straight line of openings,wherein the steps it" are supported by means of the The steps k have here the form of blocks, butcorrespond in every respectto the steps is before described, and may be obtained by cutting a bar, 1', into so many pieces as there are steps required. The operation is likewise the same as before described, and willbe readily understood from the preceding description, the only difference of importance being that in this modification the steps are made elastic and yield under the pressure of the coin drawn toward the point of delivery,while by reason of their construction they cannot yield under the pressure of the coin shoved in the opposite direction.

In the modification shown in Fig. 5 the blocks or steps 70', which may be made of light wood, as well as of metal or other suitable material, are counterbalanced by weights q, substituted for the springs 7c. The steps are here carried upon the end of an elbow-lever, 76, having its fulcrum in a bracket fastened to the lower surface of the plate '6, the other end of the said lever being provided with the counterweight q. These counterweights may have the shape of bell-hammers and be combined with tuned bells or plates q, so that they will strike against the latter in successive order, and thus produce during the delivery of the prepaid article some popular song or melodyas, for instance, that in Fig. 6When they are depressed in succession by the coin being drawn across their inclined surfaces, as will be readily understood, and thus requireno further description.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- V I 1. The combination of the case having a coin conduit or chute, a bar having steps and a coin-opening, a drawer having a slot for receiving the coin, and a drawer retracting spring, substantially as described.

2. The combination of the case having a coin conduit or chute provided with a slot, a bar having steps and a coin-opening, the drawer having a slot for receiving the coin, the drawerretraeting spring, and the springhavingapin to enter the slot in the conduit or chute, substantially as described.

3. The combination of the case having a coin conduit or chute, the movable steps, the pivoted levers supporting the steps and having counter-weights (1, adapted to strike chimes located in their path, and the drawer having a slot for receiving the coin, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
